So, when I had to get a new sublimation printer I had a hell of a time getting the thing up and running. So many clogged nozzles and mismatched color profiles. The result was a lot of mugs printed with issues. Some have banding across the print so things look stripey when I didn't want them to be stripey. Some have contrast issues where the black is faded, and some just printed with the wrong colors. 
 
These have both stripes when they shouldn't, and some of the colors/contrast are really off.
The mugs themselves are FINE, but I can't charge full price for them.
